librarian | A GoAdmin plugin build a document website of markdown | Plugin library

Imagine that we are building a Library system. Our use cases might be

• Borrow book
• Look up book
• Manage membership

Imagine that we can fulfill these use cases by a librarian person or a machine. We need to realize these use cases.

1. Should we draw different use case realizations for different flows? If not, it is very different to borrow a book from a machine and a person. How can we handle it?
2. Moreover, what if we have updated version of library machines some day? (e.g. one with keyboard and the other is with touch screen) What should we do then? The flow stays the same, however the hardware and the software eventually be different.
3. What would you use to realize use cases and why?

It might be a basic question, but I failed to find concrete examples on the subject to understand what is right. Thank you all in advance.

I have a css grid layout that looks like this,

When a box is clicked is grows in height to show information about the service. What I was hoping to be able to do was the "relayout" the grid so grid wrapped around the tallest item? Instead what I have is when I an item grows that row and it's children grow with it.

What I was hoping for was if report writing was clicked it would grow and take up benchmarking space, benchmarking would move left and consultancy would wrap onto a new line?

I am using tailwind so my HTML looks like this,

Follow-up from insert page-break after all elements except the last, when position() is not reliable.

How would I achieve the following result (more info below):

How would I avoid the last page-break element in the result:

I am currently creating a react app for practice. I am curious does react render everything when we go to a new link? For eg. These are my routers

The question is as follows:

"How do I filter a datatable based on the input of a user in my shinydashboard?"

Have a look at the reproducible code below. Within the 'user' tab I allow a user to filter the standard iris dataset based on the type of species (for example setosa or versicolor). I am however unable to show the filtered datable.

To solve my problem, I have looked at multiple posts:

• Filtering from selectInput in R shiny
• Conditional filtering based on user inputs in Shiny

However, without any success. I was hoping that one of you could help me.

This is my first post on stackoverflow. I hope that it meets the rules by stackoverflow. If not, please let me know what I need to alter.

I am trying to use history.push from a react component but it is throwing an error that history is undefined.

This index.js file:

As the title states, is there a 'neat' way to set per configuration linker flag? It is not possible for me to use target_link_options() since I'm trying to link into a static library. Ideally, what I would want to achieve is to set Visual Studio's Librarian -> Additional Dependencies and Additional Library Directories and achieve the same result in XCode as well.

Here is what I've achieved so far:

My system has more functions than it is shown inside the diagram but I am trying to do it based on the scenario.

My current scenario is that the librarian/admin is trying to delete a book record from the database, normal users can access the database but they cannot access the "delete book record" function.

The flow shall be like this, the user login to the system, if he/she entered the login detail correctly the account's access level will be checked and granted different levels of access based on the account type. After authenticating the account and its access level there will be several modules of function that can be chosen, such as transaction, search, database, and report module. After the user selects the database module they then choose which record they want to see/modify such as member record and book record. Then they will select the book record they wish to delete among all of the book records that are recorded in tabular form, then will click "delete" to delete the book record, the system will show a confirmation message to ensure that the user didn't accidentally delete the record they didn't mean't to. After the deletion, they can choose to do other actions but I trying to end the scenario so I put logout right after it.

I am actually quite confused about what can be considered as a "state". I know it is somekinds of condition or situation but most of the example I found online give me a feeling that it is an action.

Is the state diagram below being delivered correctly?
